Clean Debris from Engine & Chipper
Service Interval: Before each use and every 100 hours.
The engine requires air flow to cool itself and for combustion.
Before each use, clean any debris from the unit especially from
around the air shroud intake, air filter, and muffler. Every 100
hours, remove the engine air shroud and clean out any debris
from the engine cooling fins (SEE FIGURE 8). We recommend
having this service performed by an authorized dealer.
Inspect / Rotate Shredding Hammers
Service Interval: Every 25 Hours, or As Necessary
The shredding hammers of this unit can be rotated to provide
a new cutting surface as required. The triangular hammers
can be rotated twice, then flipped over for a total of 6 sharp
cutting surfaces. The J-hammers can be flipped over once. To
inspect the shredding hammers:
1. Disconnect the spark plug wire and secure it away from
the spark plug. SEE FIGURE 12
(on page 16)
2. Remove the small circular access panel (B) from the back
of the shredder housing. SEE FIGURE 9
3. Inspect the cutting edges of the triangular hammers (A)
and J-hammers (A). SEE FIGURES 9 AND 10
To rotate or replace the shredding hammers, see the Trouble-
shooting and Repair section.
